Hydroelectricity is even cheaper than nuclear.

The problem with most renewable power sources is that they only work well in certain geogeaphic areas. Not all areas are sunny enough for solar or windy enough for wind.

What we should be doing is figuring out how to build nuclear fusion power plants. Nuclear fusion is very complicated, but it would be worth it for two reasons. First, there's no risk of a meltdown. Second, the fuel would last much longer.

Just goes to show you how politicians can screw that up, too. Norway is self-sufficient with hydroelectricity. Now they're a part of a multi-country electricity network, where they send a lot of that electricity to other countries (no carbon tax on that) and in return get back more expensive electricity (including carbon tax from "non-renewable sources"), making electricity more expensive for Norwegians.

If there's a politician involved ... follow the money.
